The principle of the ultrasonic welding machine is to use high-frequency vibration waves to transmit to the surfaces of two objects to be welded. Under pressure, the surfaces of the two objects are rubbed against each other to form a fusion between the molecular layers. Introduction Ultrasonic weldi... view more
